CORNCRIB OR SIMILAR STRUCTURE Filed Aug. 25, 1937 Patented Aug. 29, 1939 UNITED STATES PATENT OFFICE 5 Claims.

This invention pertains to structures used primarily by farmers in the storing of grain and like farm products. More particularly,-the invention relates to an improved wall construction for such structures commonly known as corn cribs.

The primary object of the invention resides in the formation of a corn crib from a plurality of substantially ring-like sections which are stacked one upon the other to form the wall of the structure.

It is also an object of the invention to provide a corn crib which may be shipped to the user in a dismantled state and assembled by the user without requiring him to: have more than an ordinary mechanical ability or to exercise extra care to align preformed holes for the reception of fastening elements.

A further object resides in the provision of a novel joint between adjoining sections which will not require the formation of holes or the passage of fastening elements through the material from which the sections are formed.

Another object is the particular flange formation of the abutting edges of the ring-like sec tions which are spaced, by the elements employed to secure the sections together, to provide for the circulation of air through the grain stored in the crib. By providing the air space between the sections, the necessity of perforating the side walls is eliminated.

By reason of the sectional formation of the walls, the capacity of the corn crib may readily be varied. by adding or removing one or more of the sections.

For a more complete understanding of the in vention, reference is to be had to the following description and the accompanying drawing in which one embodiment thereof has been portrayed.

Fig. 1 is .a perspective view of a corn crib formed in accordance with the invention;

Fig. 2 is a vertical sectional view of the adjacent edges of two of the wall-sections, the means for securing the sections together being shown in side elevation;

Fig, 3 is a similar view of the adjoining portions of the top wall-section and the sectional roof;

Fig. 4 is a horizontal sectional View taken through one of the wall-sections and shows a butt joint uniting the ends of the sheet to form. the ring-like section.

Fig. 5 is a vertical transverse sectional view through the roof and. shows the joint between the sections forming the same;

.Fig. 6 is a. horizontal sectional view taken through the doorof the structure together with the frame therefor;

Fig. '7 is a detail horizontal sectional View through a modified fo-rmiof wall-section.

Referring more particularly to the drawing, the numeral l designates the corn crib forming the invention in its entirety. This structure includes a circular side wall 2 which is provided with a door 3 and a sectional top wall or roof 4. At

the center, thecrib is formed to include a tubular ventilating column 5 which extends through the roof at the center thereof and is covered by a conical cap t. The column 5 extends downward through the center of the crib to the base supporting the same and is provided throughout its entire length with perforations to facilitate the circulation of air through the products stored in the structure.

The side wall 2 embodies a plurality of ring-i: like or annular sections 1 arranged edge to edge in superposed order to form a tubular column. Each of the sections 1 is composed of one or more metallic strips which are bent, in a tank forming or similar machine, into an arcuate shape'and have the side edgesrolled or folded to form laterally extending flanges 8. The flanges 8 are formed by bending the sheet material laterally as at 9 and then reversely twice as indicated at if] and l i. This provides the flanges with a plu- 2 rality of thicknesses and smooth rounded inner and outer edges l2 and [3. The ends of the strips are joined tocomplete the ring by butting the same together and securing thereto a narrow plate M by means of bolts and nuts I 5 and 16. If L- desired, the ends of the strips can be overlapped and secured together by bolts and'nuts. The sections 1, after being completed, are assembled by having the flanges of the various sections coupled together by means of U-shaped clips l? and bolts I8. The clip ii is positioned with one of its spaced legs 19 under the overhanging top flange of the lower wall-section while the other leg of the clip is placed over the lower flange of the section immediately thereabove. The bolt i8 is passed through a hole in the clip and between the flanges 8 of the sections and is provided at the inner end with a washer Ella and a nut 20. After a sufficient number of clips are applied and the nuts tightened, the wall-sections will be held in rigid relationship with spaces l8b between the adjacent flanges equal to the diameter of the bolts employed. This space provides: 7

tight joint.

'shape to the flanges 8.

When the structure is used to store small grains such as wheat or cats, the spaces IBb may be closed by substituting strips of iron or like material for the Washers 18a. These strips will close the spaces and provide for a continuous wall the full height of the crib.

If desired, the spacing may be increased by using bolts of increased diameter or through the use of larger clips and sleeve-like spacers surrounding the bolts.

The strips forming a plurality of sections 1 at the bottom of the crib are made shorter than the others and have the ends 1a thereof bolted or otherwise secured to door frame members 2|. These members are also constructed of sheet metal and are provided with an offset shoulder 22, adjacent their point of attachment to the sections 7, to receive the door 3. The inner edges of the door frame members include registering channels in which are slidably positioned wooden boards 23 usedto hold the contents of the crib away from the door. A tie bar 24 extends from one frame member to the other to prevent lateral separation thereof.

The roof 4 is provided to cover the open upper .end of the tubular wall and. prevent the entrance of moisture thereinto. This roof is formed from a plurality of wedge-shaped units 25 having inverted U-shaped. beads 25a formed at the side edges thereof The beads of adjoining units fit into one another and form a water- To secure the roof to the side wall, the units 25 are preferably provided with strap members 26 which are bolted or otherwise secured to the roof. The members 26 are bent downward and have their lower ends provided with a laterally extending flange 260 similar in Clips 11, together with nuts and bolts, couple the flanges on the strap members to'the upper flange on the top wall in the same manner that the wall sections are secured together. This construction provides a space 21 between the top wall-section and the roof through which air may also circulate. The width of this space may be varied by changing the length of the strap members 26.

As shown in Fig. '7, the strength of the wall sections may be increased by providing the same with vertically extending corrugations 28.

When it is desired to change the capacity of the corn crib, the roof may be readily removed and a ring-like wall-section added or removed as desired.

While I have shown and described the invention in its preferred form, I do not wish to be limited by the showing but rather by the scope of the appended claims.

What is claimed is:

1. A corn. crib comprising a multiplicity of superposed annular wall-sections, each provided with a laterally directed flange at the upper and lower edges thereof, a plurality of circumferentially spaced U-shaped clips positioned over the flanges of adjacent sections, threaded fastening devices extending through openings formed in said clips and between the flanges of said sections, and a roof disposed above the uppermost of said superposed sections.

2. A corn crib comprising a multiplicity of superposed annular wall-sections each provided with an outwardly directed flange at the upper and lower edges thereof, a plurality of circumferentially spaced U-shaped clips positioned over the flanges of adjacent sections, bolts extending through openings provided in said clips, said bolts projecting between the flanges of the sections and serving to space the same, the inner ends of said bolts being provided with a washer and nut, and a roof secured to the upper of said superposed sections.

3. A corn crib comprising a plurality of superposed annular wall sections, each provided with an externally directed flange at the upper and. lower edges thereof, a plurality of circumferentially spaced U-shaped clips positioned over the flanges of adjacent sections, the inner surfaces of the legs of said U-shaped clips converging toward the base thereof, and means extending through said clips and between the flanges of said wall-sections for drawing said clips into clamping engagement with said flanges.

4. In a corn crib, a plurality of superposed horizontally positioned annular sections, a laterally extending flange formed at the upper and lower edges of each of said sections, the flanges of adjacent sections being disposed in vertically spaced planes, securing elements positioned in substantially parallel relationship with said flanges and extending through the spaces beof adjacent sections being disposed in vertically;

spaced planes, threaded securing elements extending through the spaces between said flanges, and a separate U-shaped clip carried by each securing element, the spaced legs of said clips extending over said flanges to prevent separation thereof.
